Method Detail

writable

public boolean writable()

Description copied from class: Vec

Default read/write behavior for Vecs. AppendableVecs are write-only.

Overrides:

writable in class FileVec

addAndCloseChunk

public void addAndCloseChunk(Chunk c,
                    Futures fs)

close

public void close(C1NChunk c,
         int cidx,
         Futures fs)

chunkIdx

public Value chunkIdx(int cidx)

Description copied from class: Vec

Get a Chunk's Value by index. Basically the index-to-key map, plus the DKV.get(). Warning: this pulls the data locally; using this call on every Chunk index on the same node will probably trigger an OOM!

Overrides:

chunkIdx in class FileVec

readPut

public static Key readPut(java.lang.String keyname,
          java.io.InputStream is)
                   throws java.lang.Exception

Throws:

java.lang.Exception

readPut

public static Key readPut(Key k,
          java.io.InputStream is)
                   throws java.lang.Exception

Throws:

java.lang.Exception
